WILLIAM BECKER'I, OF ALLEGHENY, PENNSYLVANIA.

COMBINED WAGON JACK AND TRUCK.

bSPECIFICATION forming part of Letters Patent No. 386,913, datei-.l July3l, 1888.

Serial No. 270,656. (No model.)

To aU' whom it may concern:

Beit known that I, WILLIAM BEOKERT, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inCombined Wagon Jacks and Trucks; and I do hereby declare the followingto be a full, clear, and exact deseription of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to a combined wagon jack and truck especiallydesigned for wagonmakers and painters use, although it can be used withequal success for various other purposes.'

The object of my invention is to provide a workshop appliance capable ofbeing extended or contracted to adapt itself to any size wagon or otherobject to be supported, and which can be moved about from place to placewith facility when in use.

Vith these ends in view my invention consists in the peculiar featuresand combination of parts more fully described hereinafter, and pointedout in the claims.

Referring to the accompanying` drawings, Figure l represents a sideelevation of my invention; Fig. 2, a plan, and Fig. 3 a modification.

The main frame consists of telescopic scctions a I), the formerconsisting of a hollow tube and the latter an iron rod. The extremitiesof both these sections are rigidly held in T-sockets c. The tubularsection a is provided with a collar, d, containing a thumb* screw, e,whereby the sections may be fastened in any desired adjustment. rIhiscollar d is added to give a larger bearing-surface to the screw-threadin order that the screw will have a stronger hohl. Tubular standards fare screwed or otherwise fastened in the top openings of the sockets c,and the upper end of each standard is provided with a threaded nut, g,which receives the screw It. Swivelcd to the top of this screw is asaddle, fi, for the reception of the wagon axles orrunning-gear. Theusual pin-hole, j, is made through the upper part ot' the screw by meansof which it is turned.

The four corners ofthe frame are supported upon rollers or casters k,which maybe double or single, as desired. These casters are providedwith conical shanks l, operating within bearings m,rigidly screwed inthe lower openings ot' the sockets c. In order to prevent thc castersfrom dropping out when the truck is lifted from the door, I provide theupper end of each shank with a screw'thread and nut, a. These bearings mare provided with a polygonal exterior for the reception of a wrench, bymeans oi' which it is screwed in the lower opening in the socket.

In Fig. 3 I have shown a modification in which my device is given atriangular form. This enables inc to build it one-third cheaper than therectangular form shown in Fig. 2. Besides being made cheaper by givingit a triangular sha pe,its weight is correspondingly decreased, which isalso important when my device is only needed for light work.

Any suitable form of liftingjaek may heapplied to the corners of theframe in place of thescrew-and-socket mechanism,and also many otherslight changes which might suggest themselves to a skilled mechaniccould be rel sorted to without departing from the spirit and scope of myinvention; hence I do not limit myself to the exact construction shown.

In using my device for supporting a wagon I roll it under the same untilthe jacks come beneath the axles. The wagon is then jacked up, afterwhich it can be rolled about in any direction. \Vhcn it is desired toextend the truck to occupy a larger space, it can be done by looseningthe thumbscrews c, which permit the telescopic section a 7) to beextended. Thus it will be observed that my invention maybe applied tovehicles of various sizes. Besides being capable of raising and loweringto any desired height or inclination,it will enable the operator to movethe wagon laterally in any direction to facilitate his work.

When the device is notin use/,it can bc readily contracted to occupy asmall space for convenience in packing or shipping. The tele seopicsections and other portions can be made oi' ordinary gaspipe or plumbersmaterial, and the whole can be constructed at small cost, while at thesame time it will be strong and durable.

VlnIt I claim as new, and desire to secure by Letters Iatent, is-

1. In a combined jack and truck, a rolling telescopio frame providedwith jacks, substantially as described.

2. In a combined jack and trucl?, two orA more jacks connected togetherby extensible 5 sliding bars arranged to slide one past the other in atelescopic manner, substantially as described.

3. In a combined jack and truck, two or morejacks connected together andmade adro justable in relation to each other by means of telescopicrods, substantially as described.
